Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 137480, here are decompositions:

  • 3 + 137477 = 137480
  • 37 + 137443 = 137480
  • 43 + 137437 = 137480
  • 67 + 137413 = 137480
  • 97 + 137383 = 137480
  • 127 + 137353 = 137480
  • 139 + 137341 = 137480
  • 229 + 137251 = 137480

Showing the first eight; more decompositions exist.

Possible US patent number

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 137,480 and was likely granted around 1872.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 137480 first appears in π at position 137,854 of the decimal expansion (the 137,854ordinal-suffix:th digit after the integer 3).

Search range: the first 1,000,000 fractional digits of π. Any 6-digit-or-shorter string is virtually guaranteed to appear in there — the more interesting signal is the position.
